STRIP-METAL-FINISHING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 716,322, dated December 16, 1902.

metal with a minimum amount of labor and` expense.

`My invention consists, primarily, of a revolving carrying-Wheel, a friction-belt carried upon the periphery of said Wheel and adapted tol coact with the wheel to move the strip past trimming mechanism, and of means .for adjusting the working parts ofthe machine.

My present invention is an improvement on that described in my Patents No. 670,352, dated March 19, 1901, and No. 684,485, dated October: 15, 1901, for strip metalnishing machines. p

In the accompanying drawings, forming part of this specification, Figure l is a side elevation of my improved machine, and Fig. 2 is a similarpviewtaken toward the other side of the machine.

In the drawings let A represent the frame of the machine; B, the carrying-wheel, which is journaled at 2`by the shaft3 upon the frame. The wheel is provided With the' gear 4, with which the drive-pinion 5 meshes. ion is mounted upon the drive-shaft 6, which is journaled upon the frame and revolved by the drive-pulley 7. The carrying-wheel is adaptedto move the strip ,forward on its periphery 8 by means of the friction-belts O and D. The belt C is passed around the pulleys E and F and the beltD around the pulleys G and H. These four pulleys are revolved by the gears 1, which mesh with the gear 4. The object of the belts traveling forward upon the periphery of the carrying-wheel is to present the strip to the trimming mechanism J. Thetension of the belts upon the carrying- Wheel.V is `regulated by `means of the handscrews 9, which are part of the adjusting mechanismsK and L. These adjusting devices are similar ih construction and consist of the guide-bed l0, upon which the yoke-bars 11 are fastened by means of the bolts l2.. The pulleys E and G are respectively mounted upon the shafts 13, which in turn are journaled on the yoke-bars. By turning the handscrews 9, each threaded in the flanges 14 and socketed at 15 in the yoke-bars, the pulleys E and G are moved forward and backward upon the beds 10 and the tension of thlebelts is increased or decreased upon the periphery of the carrying-wheel.

The trimming mechanism .I consists of the cutting-knife 16, which is fastened upon the carriage 17 by means of the bolts 18. The cutting edge 19 of this knife is adjusted toward the surface of the moving strip L by means of the lever-arm 2O and the belt 2l. The carriage 17 is pivoted upon the frame at 22. The lever-arm 20 is attached to the pivotshaft 23 by means of the split collar and bolt 24. The free end of the lever-arm is adjusted by means of the screws 25, which pass through the frame and the bracket 26 and impinge against the arm. By turning these screws the carriage 17 is tilted, so as to adjust the cutting edge of the knife. The adjustingbolt 2l passes through the frame at 27 and impinges against therlower face 28 of the carriage. any lost motion of the carriage 1,7 or any spring on the part of the lever-arm 20, so as to more minutely adj ust the cutting edge of the knife against the surface of the moving strip. I have found in practice that this adjustingbolt 21 is an essential element in connection with the construction of the trimming mechanism shown in the drawings.

The strip L to be' finished is received into the machine on the bed 29 and the antifriction-pulley 30. This antifriction-pulley is journaled upon the free ends of the arms 31 and provided with the flanges 32 to guide the strip upon the bed. The arms 31 are pivoted at33 upon the bed and are held in norm al position, so that the revolving peripheral surface of the antifriction-pulley is held in substantial alinement with the receiving-surface of the bed by means of the bolt and spring 34 and 35. The bolt 34 passes through the opening 36, and if by accident the moving strip be checked in passing into the machine the antifriction-pulle'y springs down and tends to prevent the straining and breaking of the strip. The surface of the bed 29 is also in The object of this bolt is to take up IOO substantial alinement with the periphery of the forwardly-moving carrying-wheel.

In operation the driving parts of the machine are revolved and the strip moved in the direction indicated by the arrows. The strip L is drawn into the machine by the antifriction pulley and the receiving bed 29 and moves between the portion 37 of the frictionbelt C and the periphery of the carryingwheel B. The surface of the strip is'then cut by the knife 16, which is part of the finishing mechanism J. The strip continues to move between the periphery of the wheel and the belt D and is finally delivered from the wheel and wound upon the spool M. This spool is journaled by means of the shaft 38 on the bracket 39, which is attached to the frame by means of the bolts 40. The shaft 38 carries the drive-pulley 4l, which is revolved by means of the belt 42. This belt passes around the pulley 43, which is mounted upon the shaft 3 of the drive-Wheel from which the spool M receives its motion.

Having described my invention, what I claim as new, and desire to protect by Letters Patent, is

1. A machine of the class set forth, consisting in combination with a carrying-wheel, of a belt adapted to travel upon the periphery thereof, pulleys for the belt, a frame upon which said wheel and pulleys are journaled, means for adjusting the tension of said belt, means by which the pulleys and carrying- Wheel are revolved forward, a trimming-knife at the delivery end of said belt, a carriage to which said knife is attached, said carriage being pivoted upon said frame, a lever-arm attached to the carriage, means for adjusting the free end of said arm and means for taking u'p lost motion between said carriage, arm and frame.

2. A machine for finishing strips of metal, consisting in combination with a carryingwheel journaled upon a frame, of a plurality of belts in feeding contact with said wheel, means for adjusting the tension of said belts, a trimming-knife between the belts, pulleys around which the belts are passed, said pulleys being journaled on said frame, means for revolving said wheel and pulleys, a carriage pivoted upon said frame to which said trimming-knife is attached, a lever-arm by which the carriage is tilted so as to adjust the cutting edge ofthe knife with relation to the periphery of the wheel, and means for adjusting the carriage to take up lost Inotion of the carriage and lever, for the purposes specified.
